Background In the existing driving or flywheel system relying on elastic energy storage release, technical bottlenecks such as low system integration level, poor transmission reliability, low energy utilization rate and the like are generally faced, and the following core pain points are generally presented: ① . The structure is complex and the energy consumption is high. After the energy storage driving unit does work, an extra reset mechanism or external power (such as a driving motor) is often needed to realize retraction and multi-station switching of an executing piece, so that the volume and the control complexity of the system can be increased, and the energy storage density is very limited in a single axial energy storage mode depending on a spring. ② . The decoupling of the transmission and the timing coordination are difficult. In a mechanical system running at a high speed or having a large inertia, when a driving action is finished and an executing piece needs to be disconnected from a main transmission chain, mechanical interference, dragging recoil or tooth end collision and the like are very easy to occur, and a series of complex actions such as energy storage maintenance, accurate triggering release, acceleration acting, indexing transposition and the like are difficult to realize smooth and interference-proof time sequence self-adaptive matching on a pure mechanical level.
